Can we change the Memory capacity that we simulate? #17

liuty10 commented 6 years ago

Since the capacity of PCM can be larger than DRAM, can we set the NVM to be larger than the DRAM when we do the simulation?

Thank you very much.

Hi @liuty10 , No, you cannot define memory sizes. The emulator makes use of physical memory (and NUMA nodes distance) to emulate NVM latency. I recommend keeping your data structures in your available RAM to avoid memory swapping, which will possibly affect the modeling accuracy.

Get it. Thank you very much @guimagalhaes
